COMPOSITION or MATTER Fem MLAKING BATiiEY BDXES COIL BOXES, AND OTHER SIMILAR LES.

No Drawing, Application filed September To all whom it may concern: 7

Be it known that I, LYMAN M. COOPER, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Compositionof Matter for Makin Battery Boxes, Coil Boxes, and Other imilar Articles; and declare the'following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanyin drawings, which form a part of this specification.

My invention relates to a new and useful composition of matter for use in the manufacture of battery boxes, coil boxes, steering wheel rims and other similar articles formerly made of wood. The principal object of the invention is to utilize waste products in the composition so that the completed article may be produced very cheaply and yet -be of greater strength than a similar article made of wood. The composition consists of the following ingredients combined in substantially the proportions stated viz:

Leached wood ashes. air dried lquart.

Air slacked lime 2quarts. Linseed oil }pint.

A Binder such as Portland cement,

pressed to approximately thirty tons per square Inch in the mold thereby producing an article of great density and of rock like hardness which has about the lightness of wood.

' 'I The binder may be either Portland cement,

calcium sulphate or the like, the object being to provide a material which will cement the several ingredients together and fill the small interstices in the body of the material making a close grained and dense article 16, 1920. Serial No. 410,621.

when formed. The body may be either sawdust, ground paper, ground leather, or other waste material which may be utilized in the compositlon and which costs practically nothing and as the main body of the com- 1 position is of this material, the formed ar ticles are made very cheaply and can be produced for considerably less cost than a similar article of wood and the formed article also having the added advantage of being formed in one homogeneous piece.

One of the most important features of this invention is that the articles after being pressed are ready for use and require no baking or drying as is customary with many compositions. Enough linseed oil must be added to allow the material to be fed through the pug mill but the linseed oil is not added in sufficient quantity .to make the material plastic and dries out while the article is being formed or soon thereafter without changing the character of the composition. This composition is particularly satisfactory when formed into battery boxes, the acid from the battery having practically no effect on the composition and as the box with this composition is formed of one piece without seams it is not only acid proof but waterproof as well and will not crack, leak or come apart. This composition also proves very satisfactory for making coil boxes, the box being without seams and waterproof proves a very satisfactory protection for coils and other devices of like nature which require a waterproof container.

From the foregoing description it becomes evident that articles made of the ingredients mentioned ma be more quickly and cheaply made than articles of similar nature formed of wood, the material at the same time being waterproof, of greater strength and greater hardness and density than wood.

Having thus fully described my composition what I claim and desire to secure by Letters Patent of the United States is- 1. The herein described composition of matter comprising leached wood ashes, air slaked lime, linseed oil, Portland cement and sawdust substantially as and for the purpose specified.

2. The herein described composition of matter for use in the manufacture of batte boxes, coil boxes, steering wheel rims and like articles comprising air dried and a i f leached Wood ashes; air slaked dime; li1ise'ed--- oil, a ceinntitious filler and a cornminuted waste material as and for the purpose de scribe'rhr; i. 4 5 3.
